基于燃油平均值模型的燃气(CNG)发动机模型

A CNG Engine Model Based on Mean Value Engine Models

计算机仿真模拟技术在发动机电控系统的开发过程中受到越来越广泛的重视 ,而计算机仿真模拟系统的核心是发动机模型。作者介绍了燃油平均值模型 ,并在此基础上进行改造 ,建立了燃气 (CNG)发动机模型。对燃气机模型和汽油机模型进行了MATLAB/SIMULINK下的仿真 ,仿真结果表明 。

Computer Simulation is more and more attached importance to development of ECU of engine, the hardcore of Computer Simulation System is Model of Engine. In this paper, a CNG engine model based on Mean Value Engine Models are developed. The model was run on MATLAB/SIMULIN, the result shows that this model is precision enough to used in development of ECU of engine.
